Silver Palace Game Modes: Endgame, Dailies & Side Modes

Silver Palace's Dichotomy beta has two endgame modes: Hilbert's Hotel, a weekly roguelike, and Thought Experiment, a 10-floor timed combat climb. Case Review adds a daily boss farm. Around them sit Curious Deductions, the branching mystery cases, and the Free Time minigames. This guide maps each mode: what it is, how often it resets and what it pays, using Rexlent's 100% clear of the second beta and Pyrrh Gacha's daily-routine guide, checked against Elementa's official posts.

Beta data: everything here comes from the Dichotomy beta (CBT2, 23 July to 13 August 2026). Silver Palace launches on 14 December 2026 (UTC+8) on PC, PS5, iOS and Android, and Elementa's August feedback post lists combat and interface changes still to come.

What game modes are in Silver Palace?

The combat modes all sit under the Agenda menu. Shrike's beta footage shows its Challenges tab as a list of farming groups: Daily Routine, Potential Exploration, Implement Overhaul, Method Mastery and Case Review, each stage costing Vitality.

What is Case Review in Silver Palace?

Case Review is the daily boss farm. Pyrrh puts it among the first things to spend Vitality on each day (2:59), because it drops the boss materials that take a character's talents, called Methods, past a certain level. On the Agenda screen the Case Review row lists Methods Study Essentials as its drop.

The rule is simple. You can fight the bosses as often as you like, but you can claim only one reward group per day. Rexlent puts the yield at about five boss materials a day at the highest tier they reached (7:27), and says the beta had two bosses on rotation: Cinderella and Vita et Mors. Their advice is to keep Vitality for it every day: the cap is daily, not weekly, so a skipped day is a lost claim.

The bosses play by the normal combat rules. In Rexlent's Cinderella fight (8:50), a yellow circle marks an attack to parry and a red one an attack to dodge, as Elementa's Combat Edition post describes.

Where do Twin Argent Strands come from?

Twin Argent Strands are the rarest upgrade item in the beta. Daily Case Review gets a character's Methods to level 9; the step from level 9 to 10 needs a Twin Argent Strand (Rexlent, 7:39).

Pyrrh explains where they come from (5:17). You buy them with Antique Coins, and the main source of Antique Coins is City Property, the real-estate minigame. In the second beta the shop sold one Twin Argent Strand per month. Pyrrh notes that players hoped for more ways to earn them, and that this is beta pacing.

Rexlent's wording, exchange them "once you have enough", leaves open whether one level-up takes more than one strand. Either way, a level 10 Method is a long-term goal at beta pacing, so decide which character gets the first strand before you spend Antique Coins elsewhere. The character progression guide covers the rest of the Methods path.

What is Thought Experiment?

Thought Experiment is the permanent endgame climb: 10 floors, each worth three stars for clearing fast, for 30 stars in all (Rexlent, 12:57). The early floors take one team. Footage from 银Khye shows a second team slot from Ongoing Project 5 onward, earlier than the floors 9 and 10 Rexlent mentions. Rexlent says the in-game rules promise a second, recurring version that resets on a schedule; the beta only had the permanent one.

Elementa used it as a skill check: the Dichotomy combat survey required clearing "Thought Experiment - Ongoing Project 7". In the first beta the equivalent gate was Deep Cognito tier T7. Floors, timers, bosses and rewards are covered in full in our Deep Cognito and Thought Experiment guide.

What is Hilbert's Hotel in Silver Palace?

Hilbert's Hotel is the weekly roguelike, and Pyrrh calls it the biggest weekly reset (6:06). Each week a set of missions pays gacha currency. Rexlent says two runs clear them all, for 900 Reactor Crystals a week (21:10). One pull costs 360 crystals, so a 10-pull takes four weeks of Hilbert's Hotel alone.

You do not have to finish a stage to earn weekly progress. Pyrrh's tip is to start as soon as it unlocks, even at low difficulty, because the Weekly Earnings counter fills from partial runs too. In Rexlent's lobby the counter reads 0/3000, and the hotel level shows Lv. 20, Level Maxed.

Membership Privileges: the permanent upgrades

Between runs you spend currency on Membership Privileges, a node tree of permanent bonuses. There are 22 nodes in the beta. Rexlent says each node costs 100, and that once the hotel is maxed you earn about one node per run (21:27). The node in the frame below, Welcome Bonus, adds 100 Hilbert's Hotel Vouchers to your starting funds.

How a run works

The beta had two stages, with a third locked. Each goes up to difficulty level 60, and Rexlent says they differ only in the final boss (21:45). The twist is the party. You control one character. The other three are supports you call in with a QTE once you have the charges, for an attack or a crowd pull, and they never become playable.

Rexlent and Pyrrh describe the supports slightly differently. Pyrrh says they never actually take the field; Rexlent talks about summoning them to fight on the battlefield. Read together: a support shows up when called, but you never control it.

A run starts with a draft. The frame below is the Select Catalysts screen, where you pick one Catalyst before the first room. These Catalysts are run upgrades that last one run. They are not the Reactor Catalysts you equip in the gear menu, covered in the Catalysts guide.

Picking the same upgrade again levels it, and some evolve into stronger versions. Rexlent rerolls at the start for character-specific upgrades for their main, such as faster Ultimate charge and more Ultimate damage for Cinderella (22:26). Deeper in, a fixed supply stop has three counters: an HP restore in the middle, stat cards on the right, and the Catalyst Shop on the left. They buy every stat card (24:14).

Which characters work in Hilbert's Hotel?

Rexlent runs Cinderella as their main and calls in Cynthia II as often as they can, because her support attack pulls every enemy into one spot. Alf is their breaker: by their count three shotgun calls stagger most enemies (23:50). For their second run they swap in Bentham, a 4-star, to show the mode does not need 5-stars (27:11).

Support calls are paid for from the Reactor gauge. That is why a fast-hitting main matters here: Rexlent says Cinderella refills the gauge quickly enough to keep calling Cynthia II on repeat (24:00).

After the final boss, a door marked Bonus Challenge leads to an optional, much harder fight. Rexlent remembers a one-time reward for it and nothing after that (25:34). They also say you can spend stamina at the end of a floor to claim extra rewards, or just leave.

How do Reactor Energy and Tactical Assault work in these modes?

Every combat mode runs on the same switch system. When you swap characters with Reactor Energy banked, the incoming character performs a Tactical Assault and one charge is spent. Rexlent's HUD shows the counter at two (11:20). Fan-compiled data puts the cap at three. Pyrrh adds a trick for solo play (7:33): press the number of the character already on the field to fire their Tactical Assault without switching.

That matters most in two places:

• Thought Experiment. Each team carries a Reactor, which adds bonuses when a Tactical Assault fires, such as extra damage for 16 seconds. Rexlent says the Reactor can make or break a team, and that Quick Equip fits one to your main damage dealer (13:49).
• Hilbert's Hotel. Your three supports are QTE calls paid for from the Reactor gauge, so the mode rewards a main who refills it fast.

Our combat style guide explains which roles build charge and Stun fastest, and the Resonance guide covers the attribute side.

What are Curious Deductions?

Curious Deductions are the detective side of Silver Palace: standalone cases worked out on the Evidence Board, with more than one ending. Elementa's Curious Deductions Edition post (26 July 2026) introduced the first, The Resurrection Mystery: a scholar's death, a wound that vanishes and a legend hanging over a secluded manor.

The official rules are short:

• you can run as many deductions as you like until you reach an ending you accept;
• Restart Deduction wipes Evidence Board progress so you can chase another ending;
• only one ending is the truth, and reaching it unlocks a unique collectable and an achievement.

Elementa's 22 August feedback post promised more cases like it. None of the creator videos we used plays a Curious Deduction on screen, so this section rests on the official text alone. We will add footage once a creator records one.

What do you spend Free Time on?

Silver Palace has two energy bars. Vitality pays for combat farming: boss materials, character and Motive EXP, and Ounces. Free Time pays for the minigames. Pyrrh lists three in the second beta (3:48):

• Scarlet Gambit, a card game Pyrrh compares to Balatro. Its stages get harder as you climb, and Pyrrh's tip for the late ones is to build Flushes;
• Coffee House, a timed rush making drinks for customers. Pyrrh found it harder on wider screens;
• horse racing.

Three more daily systems sit beside them. City Property builds income over time and unlocks an Assistant that hands out free resources, pull materials included, every 12 hours in the beta. City Roaming, in the Agenda, is a daily task list Pyrrh likens to Genshin Impact's commissions. Acquaintances is the friendship system, with a daily gift limit per character. Pyrrh starts all three as soon as they unlock; our beginner guide has the full day-one routine.

Can you make combat easier?

Yes. Silver Palace has a Casual Mode next to the standard Classic mode, set in Settings - Combat. Pyrrh says the game even suggested they switch when they struggled (1:48). What it changes, and what is still unconfirmed, is in our Casual Mode guide.

What to do every day and every week
